Newbe question here.

A little history.

I'm midpoint through my first full summer with my newly acquired 35 yr old neglected 1/2 acre pond. The pond has an abundance of muck caused by accumulated leaf debris. Very little silt from runoff. This spring I added 11 lbs. of Tilapia to try reduce the amount of algae that I had last year and they are doing great. I haven't had to rake out any algae so far this year.

Other than the TP I have few LMB and many BG and BC. The TP are reproducing like crazy.

Now the question.

Now with very little algae my water has a brown tint to it. This spring it was very clear. It's not a light brown clay but darker. I did do a jar test and was able to clear it with some alum. My thought is maybe the TP ran out of algae and are now eating/stirring up my muck. Which is a good thing and over time my water should start to clear.

Any thoughts?
